HAAS ST20Y CNC LATHES
Specifications & Market Value

Technical Description
This CNC lathe is engineered for high-precision turning applications with a 2" bar capacity and an 8.3" chuck size to accommodate medium-sized workpieces. It features a powerful 20 HP spindle motor running up to 4,000 RPM, complemented by a sub-spindle capable of 6,000 RPM, enabling efficient and versatile machining operations. The machine offers a robust X-axis travel of 9.3" and a Z-axis travel of 21", allowing for a maximum turning length of 21" and a maximum swing diameter of 31.75", suitable for a wide range of part sizes. The rapid traverse rates are optimized at 472 IPM on the X-axis and 945 IPM on the Z-axis, improving cycle times and throughput. Equipped with a 12-station turret, this lathe supports multi-tool setups to enhance machining flexibility and reduce tooling changeover. The coolant system includes a 55-gallon capacity tank for effective thermal management during cutting. Weighing 10,500 lbs, the machine is built for stability and heavy-duty operation, minimizing vibration and ensuring consistent dimensional accuracy. This lathe’s specifications position it well for high-volume production environments requiring precise, repeatable manufacturing of cylindrical components with complex geometries and tight tolerances.
